Overview

Distribution

Range Description

This species is endemic to Andalusia and is widely distributed in the mountain ranges of Cazorla, Segura and las Villas. Its known range has diminished because some subpopulations are now considered to be separate species. There are 10 subpopulations, but two of them have not been refound. Also found in the mountain ranges of Castril (Granada), Mágina (Jaén) and in the Jaén Mountains. In this last one the individuals have different characters and may represent a different species.
